The patented Showersmart regulator is easily fitted to most showers and reduces the amount of water used by stabilising water flow, regardless of pressure.

Trials show that the average saving in the UK would be £45 per year per showerhead - and the company says buyers will recover the cost of the regulator within six months.

Key markets for the company will be hotels, hostels and anywhere else where there are multiple showers.

Cenergist were backed by a six-figure mezzanine loan from the North East Growth Plus Fund to become the exclusive European distributor for the Showersmart HL2024 flow regulator.

The fund is managed by FW Capital and their investment executive Keith Charlton said: “FW Capital’s backing has provided this dynamic young company with the capital to fund its expansion with a product that has significant potential and a clear market niche.”

Cenergist MD Mitesh Dhanak has worked in the energy sector for the last 15 years and he believes that Showersmart provides a great opportunity for the company to move in to new markets.

He said: “We’ve been keen to diversify for some time and a proven product like Showersmart will enable us to offer landlords and property owners a practical and affordable energy-saving solution.

“Securing the right investment was key for Cenergist and the mezzanine structure FW Capital came up with took in to account our revenue and other projections and provided us with the flexibility we were looking for.

“We’re really excited about Showersmart as we believe it will strengthen the business and widen our reach.”

Established in 2012, Cenergist provides energy consultancy services to businesses and organisations, helping them to reduce their carbon footprint and energy costs.

Previous projects include the design and delivery of multi-million pound communal heating systems for clients such as Bupa and Hackney Homes. The company recently won a contract with Bernicia Homes to improve the energy efficiency of a 46-flat block in Gosforth, Newcastle.

North East Growth Plus Fund is part of the £142.5m Finance For Business North East Fund and can invest between £350,000 and £1.25m in a single round in established North East-based businesses.

Keith Charlton, who structured the mezzanine loan, said: “Cenergist’s management team has already used its extensive experience and expertise to establish an impressive track record and enviable UK costomer base. They understand their industry very well and have a clear expansion strategy.”
